CARDlNG-MACHINEr SPECIFICATION forming part of Letters Patent No. 761,427, dated May 31, 1904.

Application filed mber 30, 1903.' Serial No. 187,236. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES SURPRISE, a citizen of the United States of America, and a resident of Stockport, Columbia county, and State of New York, have invented certain new and useful Improvements in Oarding Ma chines, of which the following is a specification.

My invention relates to carding-machines for textile fibers; and it consists of a presser device combined with the doifer or any other moving card-surface of the machine in such manner as to .press the card-teeth just in ad- Vance of the comb or other delivery of the sliver and force the seeds, dirt, and other foreign substances down into the space below the points of the teeth and lodge them to let the sliver or fleece of cotton or other fibers come off the dofler or other card clean, while the saidforeign substances remain until the card is cleaned from time to time, as hereinafter described, reference being made to the accompanying drawing, which represents end views of the cylinder and doifer and transverse sections of the dofler-comb and of the presser of my invention.

A represents the card-cylinder, Z) the dolfer,

I and 0 the dofler-comb, of an ordinary cardingmachine.

' Just below the comb I applya presser d in.

suitable relation to the dofler for the teeth to run against it and be pressed back or down, as shown, so that the seeds, dirt, and other foreign substances Will be forced back into the space behind or below the fibers of the fleece and lodged clear of the teeth of the doffcr-comb and free of the fibers of the fleece being combed or otherwise cast off, leaving it clean, such dirt and other matters remaining to be removed from time to time when the dolfer or other card is cleaned. This presser consists of a smooth rod or shaft, of steel or other hard substance, so set on the card-frame and adjusted in relation to the dofler as to press the wire teethvslightly and force the seeds, dirt, or other foreign substances down below the points of the teeth, as and for the purpose before stated. It will be fixed adjustably toward and from the teeth for enabling 5 it to be shifted for proper adjustment.

The presser may be of cylindrical form and may revolve either by contact with the dofler or it may be geared in any approved Way for causing rotation and may be run either faster or slower than the doffer or at the same rate of speed, or it may be stationary. It may be made of any suitable material, and if stationary may have any approved form of crosssection and may be attached to any convenient part of the machine. Such a presser may be applied to any of the card-rollers or to the cylinder itself with benefit; in fact, to any of the moving surfaces .of the carding-machine having wire teeth.

Although the presser presses the fibers as well as the seeds and dirt in, the valuable fibers more or less entangled with the teeth and with the sliver being combed ofl spring out again, all of them that are of use, while the seeds and dirt remain. in.

- The presser is carefully adjusted, so as to make the seeds just clear the teeth of the doifer-comb.

In practical use on several machines for several months fifty to ninety per cent. more of refuse, according to quality of stock, has been taken out than from like cards running without such pressers, as was proved by comparing theweights of the respective wastes. In these comparative tests about an ounce a day was taken from the doffer by the hand-card from the machine not having the presser, while from those having the presser from eight to twelve ounces per day have been taken.

When it is understood that the solid seeds, chips, scraps, and most of the dirt are taken out of the ,stock by the dusterin the picking-room, yet the dead-head seeds or husks, with some fibers attached to them, escape the duster and picker and go into the card and make frequent stops and breakages in the after processes-namely, the spinning and weavingor if in the knitting-mill make holes in the finished web, often converting good firsts into seconds, bringing lower prices, it will be seen there are two economiesone in time and the other in the finished product.

WhatI claim as my invention is 1.
